Previously Mt. Igneus was indeed not available for teleportation. It was around the time Fluoruma City and Igneus Depths opened when some players found that Mt. Igneus became available for teleportation, but given that it was NOT before, it has to be a bug. It is a minor one, so maybe the Developers won’t fix it until a later time.

Anyway, sorry for what happened and for now I kept Igneus Depths as a Sp. Atk Hotspot. In terms of efficiency though, Hiker Darrel and Mt. Igneus fall behind too much. Remember how we replaced Route 7 and Rosecove Beach grass with Mountaineer Tawnya on Route 15 as HP Hotspot? It was the same reason.
